The correct relation between the packing fraction f and mass number A is -

Why are atomic masses of most of the elements fractional and not whole numbers?

Concentration terms-W/W %,W/V %, Molarity,Molality,Mole Fraction ,PPb,PPm

Concentration terms such as mass percentage, ppm, mole fraciton and molality are independent of temperature, however molarity is a function of temperature. Explain.
